Improved fuel consumption, low noise, and dependable performance are just some of the customer benefits delivered by Perkins' new 404F-E22TA engine, designed to meet U.S. EPA Tier 4 Final/EU Stage IIIB emissions standards. The turbocharged aftercooled 2.2-L model should be of particular interest to compact equipment manufacturers, especially for construction applications. While the new model retains many of the features of other 400 Series engines, it is the addition of the common rail fuel system and full authority electronics that will provide a tangible and marked increase in performance and allow OEMs greater flexibility in tailoring the engine to specific applications. It also allows OEMs to use a smaller displacement engine in machines where traditionally engines up to 2.9 L may have been the norm, while its compact package size and sleek engine architecture, featuring a rear-mounted small diesel oxidation catalyst (DOC), allows OEMs to easily adapt the engine to machine designs across many construction applications including skid steer loaders, compact wheeled loaders, hydraulic excavators, and rollers. Performance from the 404F-E22TA has been boosted to 67 hp (50 kW) with a maximum torque of 208 N·m (153 lb·ft) at 1800 rpm, while rated speed is up to 2800 rpm. OEMs also have the option of a turbocharged non-aftercooled model, offering up to 48 hp (36 kW). Real life testing has shown a 7% improvement in specific fuel consumption previously gained at Tier 4 Interim/Stage IIIA.
